[Problem] Paired remote device's address is changed after BR/EDR pairing
-> LE pairing when it uses RPA address for LE
[Cause & Measure] When LE is paired, BR/EDR device structure is merged
to LE RPA device structure. It causes address change of BR/EDR device
and applications cannot track that device.
[Checking Method] BR/EDR Pairing -> LE Pairing with M OS Android device
